MARKING DEVICE FOR GRADING MACHINES.

Application filed May a, 1925. Serial No. same.

This application is a continuation in part of my application Serial No.720,215, filed June 16, 1924, for a grading, fieshing and eveningmachine, and relates particularly to 5 marking or stamping devices foruse in a grading machine of the kind disclosed in my said formerapplication and/or in the wellknown Nichols grading machines of which anexample is shown in the Nichols Patent 10 No. 1,130,321, dated March 2,1915.

Since neither the grading machine as a whole, nor the mechanism foractuating the marker or stamp, in and of themselves constitutes any partof the present invention, it will not be necessary to describe them here'in de tail, but merely to refer to saidformer disclosures for acomplete description. Sufiice it to say for the purpose of the presentapplication thata grading machine to which the present invention isapplicable has means for detecting the grade of successive blanks ofstock according to a thickness dimension, and a marker or stampresponsive to the detecting means for marking the blanks in accordancewith their grades as determined by the detecting means. I with themarkers themselves, and more specifically to the combination of tannagemarking wheels with the grade marking Wheel, as more fully hereinafterset forth.

A shoe manufacturer often wishes to have his soles, heel lifts or otherblanks or pieces of stock which enter into the manufacture of shoes,stamped not only to indicate their ticular tannage of the leather ofwhich they are made. Moreover, a manufacturer may use stock of a verylarge number of different tannages. It is the main object of the presentinvent-ion to produce a markingor stamping device for a grading machinecapable of accomplishing this result. 7 V

In the accompanying drawings, which illustrate certain embodiments ofthe invention Fig.1 is a sectional view of one form of the markingdevice; 7 4

Fig. 2 is a front elevation of the grade marking wheel;

Figs. 3 and 4 are front elevations of the two tannage wheels shown inFig. 1;

Fig. 5 is a sectional view of a modified form of the marking device; 7 V

The present invention has to do thickness grades but also to indicatethe par-.

Fig. 6 is a front elevation on line 6-6 of Fig. 5; and

,Fig. 7 is detail of the form of detent used in the modification shownin Figs. 5 and 6.

Referring first to Figs. 1 to.4, th e device in the form of a verticallysliding plunger, as

explained in said earlier application and patent, and which at theproper times is forced downward to impress the marking on the stock. Onthe end of shaft 12 is a pinion 14 through which thelgradewheel isadjusted by means of the usual setting mechanism in response to thegrade detecting means.

Loosely mounted on the same shaft 12, which carries the grade markingwheel 10, and located in a recess milled in the side of the support- 13,is a thintype wheel 15 similar in I general outline to the grade markingwheel 10 but having stamping or marking characters on its peripheralprojections to indicate tannages. An annular row of depressions orsockets 16 is provided on the inner face of wheel 15. Adjacent the maintannage wheel 15 is a supplementaltannage wheel 17 in the form of asegment below the center having a contour similar to any segment of themain wheel 15, the upper part being cut away and provided with a row ofdepressions or sockets 18 arranged in the arc of a circle. 19 is mountedin ahole in head 13 and is yieldingly'pressedby a spring 20 intoengagement with one or another of the sockets 16 of head 13, which is Adetent wheel 15. A similar detent 21, mounted'i'n another hole in head13,'is yieldingly pressed by spring 22 into engagement with one oranother of the sockets 18 of the wheel segment 17. The detent 19projects through the space left by the cut away part of wheel segment 17As shown in the drawings, there are twenty type projections on the maintannage wheel 15, and eight type projections on the segment 17, the endprojection 23 of the segment being left blank opposite the end socket24. It will be understood that the operator sets the tannage wheels byhand to indicate a batch or run of soles or blanks of any particulartan- 17, the number of different tannages which can be indicated bythe-combinations of characters is one hundredand sixty; and by using themain t'annage wheel alone in conjunction with the blank 23 ofsegm'ent1'7, twenty more identifying marks can be used, making in all onehundred and eighty different designations for diilerent tannages. Ofcourse this number can be varied at pleasure, within practicable limits,by varying the number of- *types on the two tannage wheels.

Referring now to the modification shown in Figs. 5 to 7, the supportinghead 13, the grade marking wheel 10, the shaft 12 and thepinion 14 mayall' be substantially as shown in the other figures. Tannage wheel 25 issimilar to wheel save that the peripheral notches 27 between the typeprojections are approximately rectangular-,instead of curved, in or derpositively toengage the detent presently to be described. The othertannage'wheel 26' is like tanna-ge wheel 25, except that if desired thenotches 27 in one wheel may be slightly j deeper than inthe other. Thetwo tannage wheels and'26 are mounte'dto turn on a boss or hub 28 on oneside of the support 13 concentric withshait 12, and are held on th hubby anannular flange '29 screwed tothe" end of the hub. A detent in theform of a slide '30 is mounted in a longitudinal channel in the support18, with its lower end engaging one of thenotches or depressions 27 of I7 wheel, but not the other, may it he desires ad-.

'- each tannage wheel 25 and 26. By making the notches 27 of one wheel alittle deeper than those of the other, and the locking jend otdetent 30opposite the deeper notches alittle longer, as show-n at-31 (Fig. 7),tl1anthe "parts of the" end opposite the shallower notches, the operatorby lifting the detentfar enough out of the notchesto clear one tannagejust one wheel while the other is held locked and undisturbed. slightadditional movement of the sliding detent will free both wheels foradjustment. 7 I

Vith the modification shown in Figs. 5 and 6, using two complete andunmutilated type wheels it is possible to provide for a much largernumber of tannage marks, using the same size wheels, than with the formshown in Figs. 1 to 1. F or example, it both wheels have a. full and"equal number of types. assumed to be twenty types as in the case ofwheel 15 (Fig. 3) four hundred difierent combinations are possible todesignate tannages, as against one hundred and eighty permitted by theuse of the segmental wheel 17 (Fig. 4). Moreover, the detent 30 bypositively locking the tannage wheels in adjusted position preventstheir being accidentally disarranged by shocks due to the actuation ofthe stamping device as a whole or by other causes. In either form of thedevice one tannage wheel may be adjusted, while the other is heldstationary by its detent.

I claim:v V

1. In a machine oftlie character described, in combination, a grademarking wheel, a support therefor, a plurality oftzinnagetmaikingwheels' mounted-on said support and adjustableindependently of said grade marking wheel and of each other, eachtannage markmg wheel having a series of peripheral notches, thenotchesin one wheel being deeper than the notches in the other wheel, and a.detent common to said tan nage marking wheels and mounted to move onsaid support into and out ot'engagement with said notches, thel'ockingendoisaid detent having a projection cooperating with the deepernotches.

2. In a machine ofthe character described,

.in combination, a grade marking wheel, a

support therefor, a: plurality of other marking wheels mounted on saidsupport and adjustable independently of said grade inarln ing wheel andof each other, each such other marking wheel having a series: ofconcentric locking sockets, one series being radially nearer the axis ofthe wheels than the other, and detent means movably Inounted on saidsupport to engage and disengage said sockets, whereby oneiot said'othermarking wheels may be unlocked and adjusted without unlocking the otheror others.
